Symon, google 'mjmods'
montdj, I was going to say get the SEIO 1100/1500 cuz you can run a SEIO controller whenever you're ready. But, I guess you've already made your mind.
IMO, it is best if you dont power cycle the Koralias. If they are like the NanoStreams or MJMods, in rare occasions, they can spin backwards for a prolong period of time during startup.
